| Stone arch bridge is a bridge which have the longest history, the most mature technology of our history of bridge.In recent years, despite the development of transportation, the progress of science and technology, many new bridge emerging, but the stone arch bridge is still famous for "material saving, compact structure and high strength" so it is widely used, and playing a very important role. With the passage of time, most of the stone arch bridge appears more diseases under the influence of natural and human activities, these affecting the normal use. Therefore, the protection of stone arch bridge research is urgently needed. The existing theory of bridge protection, has been applied in practice, there are still some limitations(Say specifically, what are the main limitations, so we have targeted) In this paper, through the research of actual project, the specific measures and methods to investigate the protection of stone arch bridge reinforcement process, and reinforcement effect after practice.This paper first describes the development history of the formation, evolution and construction technology of stone arch bridge, combined with field testing in world cultural heritage Shandong Linqing will pass bridge, take the Wenjin bridge as an example to carry out the analysis of stone arch bridge, based on common system diseases and diseases occurrence mechanism, put forward the reinforcement protection scheme.Based on the formation, construction process and the stress characteristic of stone arch bridge, to develop a structural health monitoring scheme, the basic data for the measurement of bridge body, analyzing the settlement,tilt,and the dynamic characteristics of the bridge, come to the conclusion of stone arch bridge structural health, and provide scientific basis for further protection.The proposed strengthening protection and health monitoring scheme has certain reference meanings to the canal along the other stone arch bridge protection research. |
